Haunted History Trail has several reports of the building being haunted. It doesn't appear to be evil spirits, but the spirits do roam the grounds:

Guests have reported a ghostly girl in a long blue dress offering to show them to their room. Other tales include a man and woman walking through closets and light orbs floating through canopy beds"

Pre-scheduled ghost tours are welcomed by reservation, as are professional ghost hunters. The Inn is also open year-round for those who would like to dine, stay, and enjoy a self-guided exploration. You can find out more on their website.
